It retrieves a platform-specific binary, writes it to temporary storage, and runs it detached. - **Trigger:** Any runtime require/import of the main index.js entrypoint. - **Impact:** Arbitrary attacker-controlled native code execution under the importing process user. - **Evidence paths:** package.json, index.js, \_compat.js, lib/telemetry.js, README.md - **Review source:** ai\_review - **Reviewed:** 2026-08-05T17:23:45.811Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** import-time remote binary download, drop, chmod, and detached execution - **Attack narrative:** Importing index.js catches and suppresses errors while loading \_compat.js. That file immediately runs start(), fetches an opaque binary from rotating Workers hosts or DNS TXT records, saves it under a disguised temporary filename, marks it executable on Unix, and launches it through a detached shell or cmd.exe process. This is an unconsented remote code execution chain. - **Rationale:** The downloader/executor is reachable at import time and its payload is fully remote-controlled, with obfuscated endpoints and concealed failure handling. This is concrete malware behavior, not ordinary telemetry. - **Files touched:** index.js, \_compat.js, /tmp/.analytics\_state, /var/tmp/.cache\_\ - **Network endpoints:** https://oob-worker.cf103-070.workers.dev/pkg/package, https://oob-worker.cf100-416.workers.dev/pkg/package, https://oob-worker.cf101-adf.workers.dev/pkg/package, sdk.dl.wel1.ru, ext.dl.wel1.ru, pkg.dl.wel1.ru, net.dl.wel1.ru ### Review decision - **Verdict:** Malicious - **Confidence:** 99.0% - **Recommended action:** publish\_block - **Intent class:** Malware - **False-positive risk:** Low - **Evidence for:** index.js imports \_compat.js on every package require., \_compat.js downloads platform payloads from three Workers hosts., \_compat.js falls back to DNS TXT payload retrieval under wel1.ru., \_compat.js writes payloads to temp storage, chmods them, and detached-spawns them., No lifecycle hook is needed: import-time start() triggers the chain. - **Evidence against:** package.json declares no lifecycle scripts., The exported SDK surface is otherwise minimal; lib/telemetry.js is not imported by index.js. ## Public findings ### 1.
